<p>No, you can't select the borrowck in use.</p>

<p><span class="user-mention" data-user-id="116083">@pnkfelix</span> I guess <span class="user-mention" data-user-id="116466">@Zoxc</span> wants to declare that one crate uses the old borrowck regardless what's the main borrowck in use</p>

<p>and as <span class="user-mention" data-user-id="215333">@Florian Gilcher</span> have said that's not possible</p>

<p>I wasn't sure if @Zoxc just wanted to try to throw some random code in a crate at the old borrowck</p>

<p>(of course I wouldn't be suprised if one encountered ICE's in such an attempt to shoehorn AST borrowck into a 2018 edition context.)</p>
